This 100 amp automatic transfer switch is used for transferring electrical load from a utility (normal) power source to a generator (standby) power source. Transfer of electrical loads occurs automatically when the utility power source has failed or is substantially reduced and the generator source voltage and frequency have reached an acceptable level. The transfer switch prevents electrical feedback between two different power sources (such as the utility and generator sources) and, for that reason, codes require it in all standby electric system installations. The transfer switch consists of a transfer mechanism, utility service disconnect circuit breaker and a Smart A/C module incorporating fuses and two terminal blocks for transfer switch connections.
- 100 Amp Service Rated: Suitable for 120/240V single-phase applications.
- NEMA 3R Enclosure: Designed for outdoor use, providing protection against weather elements.
- Digital Power Management Technology (DPM): Allows the generator to manage up to 4 HVAC 24V electrical loads without additional hardware.
- Automatic Transfer: Seamlessly transfers electrical load from utility power to generator power during an outage.
- Smart Switch: Monitors selected circuits and automatically supplies power when needed.
- Due to lighting and monitor differences, actual colors and finishes may vary slightly from what appears online.
